ASME SA192 Serpentine Tube For Superheater Coil Bending With Custom Specifications
What materials are used for serpentine tubes?
Typically carbon steel, stainless steel, or copper alloys depending on application.
Technical Requirements:
Straight Tubes Standard Specification For Bending: ASME SA 213; ASME SB 163; ASME A789, ASME SA268, ASME SA269, etc. Marking: Before Bending By Marking Machine All Over The Tube Length (Bent Section After Heat Treatment Without Marking) Note: Marking is also possible After Bending On The Straight Parts Of U-Bending Tube.
U-Bend Tubes: -TEMA RCB 2.31 Standard Of The Tubular Exchanger Manufacturers Association (9th Edition). -ASTM A688/ASME SA688 Standard Specification For Welded Tubes Of Austenitic Corrosion Resistant Steel Grade Designed For Feed Water Boilers. -ASTM B163/ASME SA163 Standard Techinical Requirements For Tubes Of Nickel And Nickel Alloy For Condensers And Heat Exchangers. -Customer Specifications. These are key components in heating systems, tasked with raising
steam temperature. Their main goal? Boost steam enthalpy to up the
thermal cycle efficiency in power stations.
Superheaters take saturated steam and heat it to a specific
superheated temperature. When boiler loads or other working
conditions change, it’s vital to keep the superheated steam
temperature normal and within the allowed variation range.
Looking at the power station’s thermal cycle: the higher the
initial pressure and temperature, the better the cycle’s thermal
efficiency. If they’re too low, the steam in the later stages of
the turbine gets overly humid, which can compromise safety. But
here’s the thing—superheater steam temperature is limited by metal
materials. Right now, most power station boilers cap superheated
temperatures at 540–555 degrees because of these material
constraints. To stop the steam from getting too wet in the
turbine’s rear blades, a mid-reheat system is used.
Bending Radius: From 1.5*OD(Outside Diameter) To 1500mm When Ordering Tubes With Radius less or equal to 1.5*OD, It Is Necessary To Agree Precision Of Geometrics. Straight Tubes Maximum Length:(Before Bending): 35000 mm. Leg Length: Min 1 Meter, Max. 16500 mm (For Max R=1500mm) Note: Other Size Are Available Upon Agreement. Heat Treatment: Stress Relieved After U-Bending (Bending Area Plus 300MM For Each Leg). Hydrostatic Test After U Bending: Maximum Test Pressure 600 Bar, Soaking 10 Sec. With Dematerialized Water. Compressed Air Cleaning After Hydro-Test. Packaging: In Strong Transport-Worthy Pre-fumigated wooden boxes of corresponding dimensions for each tube Length, Radius, Diameter, According To PO requirements as well as wrapped In polyethylene films With soft plastic caps on both end of Tube.
The Serpentine Tube Comply With The Following Standards: 1. ASTM A688/ASME SA688 2. ASTM A803/ASME SA803 3. ASTM A556/ASME SA556
